Gallery permission is the access an app requests to read, add, or manage photos and images stored on a device. On Android and iOS, this often means access to the user’s photo library, screenshots, and saved images.
It matters because image folders are not just personal media; they can hold sensitive material such as recovery phrases, passwords, identity documents, and receipts. Malware and spyware may abuse gallery access to scan screenshots for secrets or to quietly collect device information. Defenders should treat unexpected photo-library requests as a warning sign, especially for apps that do not need images to function. Good practice includes denying unnecessary access, reviewing app permissions regularly, and avoiding storing secrets in screenshots or photos.
